Referring to FIGS. 10 to 13. FIG. 10 is a schematic structural view of a computer system having a sensing function in accordance with another embodiment of the present invention. FIG. 11 is a schematic side view of the computer system shown in FIG. 10. FIG. 12 is a schematic top view of the computer system shown in FIG. 10. FIG. 13 is a functional block diagram of the computer system shown in FIG. 10. As shown in FIGS. 10 to 12, the computer system 1 a of the present embodiment is similar to the computer system 1 shown in FIGS. 1 and 2, except that the computer system 1 a of the present embodiment further includes an image projection module 15. The image projection module 15 is connected to the base 10 via one end of a support frame 16 and is located on one side of the first light emitting assembly 11 and the second light emitting assembly 12. Specifically, the image projection module 15 is located between the first light emitting assembly 11 and the second light emitting assembly 12. In the present embodiment, the image projection module 15 has a vertical distance Z with respect to the bearing surface 100, and the image projection module 15 has a third optical axis A3. There is an angel 03 between the third optical axis A3 of the image projection module 15 and the bearing surface 100, there is a first distance D1 between the image projection module 15 and the first light emitting assembly 11, and there is a second distance D2 between the image projection module 15 and the second light emitting assembly 12.

In the present embodiment as shown in FIGS. 11 and 12, when the image projection module 15 projects an image I onto the sensing region R formed by the first light emitting assembly 11 and the second light emitting assembly 12 on the bearing surface 100, the angle 04 between the third optical axis A3 of the image projection module 15 and the first optical axis A1 of the first light emitting assembly 11 is greater than or equal to 75° and less than or equal to 90° for example. Similarly, the angle between the third optical axis A3 of the image projection module 15 and the second optical axis A2 of the second light emitting assembly 12 (not shown in FIG. 11) is also between 75° and 90°. It is to be noted that the angle θ3 between the third optical axis A3 of the image projection module 15 and the bearing surface 100 is also between 75° and 90°. As shown in FIG. 12, when the image projection module 15 projects the image I onto the sensing region R, the image I projected by the image projection module 15 is completely located within the sensing region R, that is, the area of the image I projected by the image projection module 15 is smaller than the area of the sensing region R. In such a case, the image I is completely located within the sensing region R when the user performs a touch operation on the image I projected by the image projection module 15, and therefore, the user can experience enhanced touch sensitivity.

In the present embodiment as shown in FIG. 13, the computer system 1 a further includes a processing module 14. The processing module 14 is disposed in the base 10 and electrically connected to the image projection module 15, the first light emitting assembly 11 and the second light emitting assembly 12. When the computer system 1 a is actuated, the processing module 14 enables the first light emitting assembly 11 and the second light emitting assembly 12 to form the sensing region R on the bearing surface 100. Meanwhile, the processing module 14 also enables the image projection module 15 to project the image I within the sensing region R. The processing module 14 can adjust the area and position of the sensing region R by adjusting the angles of the light emitting assemblies according to the position and size of the image I.

In the present embodiment as shown in FIG. 13, the computer system 1 a further includes a light emitting assembly driving module 17. The light emitting assembly driving module 17 is electrically connected to the processing module 14, the first light emitting assembly 11 and the second light emitting assembly 12. When the image projection module 15 is rotated to a specified angle on a Y-Z plane (e.g., a plane perpendicular to the bearing surface 100 or a plane not parallel to the bearing surface 100) and is actuated, the processing module 14 enables the light emitting assembly driving module 17 and thereby drives the first light emitting assembly 11 and/or the second light emitting assembly 12 to rotate to a corresponding specific angle (e.g., the first angle θ1 and the second angle θ2 shown in FIG. 2, wherein the first angle θ1 and the second angle θ2 are 90°, greater than or equal to 70° and less than or equal to 90°, or greater than 90°) on the X-Y plane (e.g., a plane parallel to the bearing surface 100). For example, when the area of the image I is larger than the area of the sensing region R, the first angle θ1 and/or the second angle θ2 may be adjusted to be greater than 90° to increase the area of the sensing region R. When the position of the sensing region R is relatively far from the base 10, the first angle θ1 and/or the second angle θ2 can be adjusted to be less than 90° to reduce the distance between the sensing region R and the base 10 and increase the touch sensitivity. When the area of the bearing surface 100 is smaller than a determined value of the area of the image I, the image projection module 15 can adjust the area of the image I and the area of the sensing region R so as to make the image I locate within the sensing region R. As a result, the area of the sensing region R and the distance to the base 10 can be properly adjusted by adjusting the mutual angle of first light emitting assembly 11 and/or the second light emitting assembly 12 regardless of the size of the bearing surface 100 where the base 10 is located and the position and size of the image I. In addition, the light emitting assembly driving module 17 of the present embodiment includes at least one servo motor 171 and at least one gear assembly 172. When the light emitting assembly driving module 17 is actuated, the servo motor 171 drives the gear assembly 172, and thereby drives the first light emitting assembly 11 and/or the second light emitting assembly 12 to rotate to a corresponding specific angle on the X-Y plane.

The sensing region Rb has a short side Lb parallel to the base 10. In the present embodiment, the short side Lb of the sensing region Rb is less than twice of the distance Dn for example, but the present invention is not limited thereto. In one embodiment as shown in FIGS. 16 and 17, the short side Lb of the sensing region Rb is, for example, less than twice of the distance Dn when the Nth optical axis A1 n and the first optical axis A11 have an inward angular offset from each other. In one embodiment as shown in FIG. 18, the short side Lb of the sensing region Rb is, for example, greater than twice of the distance Dn when the Nth optical axis A1 n and the first optical axis A11 have an outward angular offset from each other. In another embodiment as shown in FIG. 19, inner edges of light sources of the N light emitting assemblies 11, 12, . . . , 1N intersect at N-1 points i_(1,2), i_(1,3) . . . , i_(1,n) on the bearing surface, thereby forming an irregular-shaped sensing region Rb having its boundary passing through the point i_(1,n).
